SOOT-ARRESTER AND DRAFT-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 787,808, dated April18, 1905.

Application filed October 22, 1904.. Serial No. 229,674.

To all 'llfll fflfil it may concern/.-

Be it known that l, OIL-\RLEs H. TI'RVER, a citizen of the UnitedStates, and a resident of the borough of Manhattan, in the city of NewYork, county of New York. and State of New York, have invented a new anduseful Improvement in Soot Arresters and Draft- Regulators, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to improvements used in flues to prevent thefalling of soot into the grate or fireplace and having as a furtherobject the regulation of the draft.

Hence one object of my invention is to prevent the accumulation of dirtin the fireplace or grate due to the tallmg soot and the soilmg of thefloor of the room and the wallpaper thereof from the same cause.

Another object of my invention is to prevent downdrafts, a frequentcause of falling soot, and other objectionable features of presentchimney construction.

A third object of my invention is to attain economy in the use of fuelby retaining heat in the room which would otherwise pass up the flue.

Other objects of my invention will more, fully appear from the followingspecification and claims.

Similar reference characters refer to similar parts throughout theseveral figures of the drawings, in which- Figure 1 is a verticalsectional view from front to rear of a chimney-flue, showing my newsoot-arrester and draft-regulator in position, the doors thereof beingclosed. Fig. 2 is a vertical sectional view of the lower deflector withthe doors open. Fig. I; is a per spective view of the lower deflector.Fig. -.l is a perspective view of one of the sections of the upperdeflector, and Fig. 5 is a perspective view of an intermediatedeflector.

In the drawings illustrating the principle of my invention and the bestmode now known to me of applying the same, 6 is the chimney-flue, and 7is the throat thereof. During the construction of the chimney there arebuilt in light metal cross-rods b, spaced apart by a distance equal atleast to the height of the upper deflector f), in order to permit thelatter being placed in position and removed therefrom at pleasure. (SeeFigs. 1 and it.) The upper deflector, as shown in-Fig. 4, is formed withcrowns 10, connected by sides 1% with the base portions 11, the outerones of which are formed with lips, as shown. The supporting end members13 are formed with flanges 12, which rest upon the crossr ds S. Theparts 10, l 1, and 12 practically close the flue: but the openings 15and H5 in the side and end members allow the passage of smoke and thegaseous products of combustion.

The lower deflector (shown in perspective in Fig. 3 and in sectionalelevation in Figs. 2 and 1) comprises a base-plate 17, which fits withinthe throat 7 and the rear and sides of which rest upon the ledge orcorbel 1b of the rear and side walls of the fireplace, while the frontlies beneath the arch of the fireplace and may be used to support thesame. This base-plate 17 is formed with a rectangular opening 19, aroundwhich rise vertical walls 20 and inclined walls 21 and 22. The wall 22is provided with a door 23, having an enlarged lower end or side 23,which rests and turns between the studs 23 and the wall 22 and beingofsuch a length that its upper edge portion rests upon the wall 21 whenthe door 23 is closed. (See Fig. 1.) The base-plate 17 is furthermoreformed with lugs 35, 36, and 37, (see Figs. 3 and 2,) between which areheld the housings 26, the end walls 27 of which are provided withopenings. \Vithin these housings operate or swing doors 25, that coverthe openings 2-f in the wall 21. The walls 27 of the housings 26 areformed on the inside with sockets 28, within which the lower corners ofthe doors take a bearing, and the doors 25 are provided with a lug 2S),perforated, as shown, to permit the swinging of the door 25 by means ofa poker or like device. To provide means for swinging the door 23, thecross-bars 30, connecting the walls 21. and 22, are formed withcol'iperating sockets adapted to receive the pivot 31 of a cam 32, theouter end 33 of which rubs against the door 23 when the cam is swung byengaging a poker or like means in the perforation in the tailpiece 34.(See Figs. 1 and 2.) The door 23 closes by gravity.

Intermediate the upper and lower deflectors just described are providedthe deflectors 38, which are retained in position by the lugs 36 and 37,as shown in Fig. 1, and which may be of different height, as showntherein. These intermediate deflectors 38 are made of thin metal,overlapping each other, and are provided each with a strengthening-rib39.

A serious objection to the open fireplace is the constant falling ofsoot and dirt from the chimney into the grate upon the hearth or intothe room, destroying the cleanliness of the floor and walls. Anotherserious obj ection is the inflow of cold air due to downdrafts, chillingthe room and bringing with air currents soot and dirt. Still anotherserious objection is the loss of heat, resulting in unnecessaryconsumption of fuel and increased eXpense. These objections are overcomeby the new soot-arrester and draft-regulator herein described and shown.The smoke and other gaseous products of combustion from the fire willreadily pass through the deflectors in the direction of the arrows shownin the drawings, so that the use of the device is not an impediment tothe necessary draft, and after the fire has attained a sufficientheadway the doors 25 are closed and the door 23 is left open, or, ifpreferred, the door 23 may be closed and the doors 25 left open. Thedegree of opening of the door 23 is controlled by the cam 32, the latterbeing adjusted to the desired position. WVhen the doors are in apartly-closed position, nothing falling from the flue above them canpass the series of deflectors. Ascending currents from the fire willforce the soot upward, while descending currents will throw the sootagainst the crowns 10, base portions 11 and flanges 12 of the deflector9, the inclined wall of the deflector 38, the upper side of the door 23,and the upper sides of the horizontal parts of the housings 26, whenceit will slide to the upper side of the base-plate 17, and the force ofsuch currenst will be spent against and dissipated by the same parts.Soot or descending air-currents striking against the wall 21 will glidetherefrom and be intercepted by the housings 26. Thus falling soot anddirt is prevented from gaining access to the part of the flue beneaththedeflectors, cold air is kept out of the room, and heat is retained inthe room. Cleanliness and economy in fuel result therefrom. When thereis no fire in the grate, all the doors in the lower deflector areclosed, thereby rendering it impossible for downdrafts to force soot ordirt past the deflectors into the fireplace or for soot or dirt to fallinto hearth or grate. In the event of the accumulating of soot or dirton the deflectors the doors in the lower deflector are removed and theupper and intermediate deflectors are removed and freed of theaccumulation of soot and dirt.

The various parts of the lower deflector, as will have been noted fromthe foregoing description, are not secured to the base-plate 17, but areloosely fitted thereto, and so most readily detachable therefrom, beingmerely slipped into place between the lugs on the base-plate or intosockets, which permit of their being readily swung in case of therotatable members.

The base-plate 17 may be built into the chimney-wall as the latter is inprocess of construction, or the base-plate may be put in place in thechimney when the latter is completed. As has already been indicated inthe preceding description, the opening 19 in the base-plate 17 is ofsufflcient size to allow of the removal of the detachable parts of thelower deflector and of the upper and intermediate deflectors themselvestherethrough, as well as of the soot.

The entire construction of my new device is of such a nature as to lenditself to the dismantling of the structure and the ready removal of theaccumulation of dirt and soot and cleaning of the parts.

As is clearly shown in Fig. 4, the walls 14 are inclined, and the crowns10 overhang the openings therein and the openings 15, therebyintercepting soot and dirt, which might otherwise pass through saidopenings.
